[Texmacs-dev] (Follow-up from texmacs-users) Plotting functions with TeXmacs graphics -> Installing development version of TeXmacs

[Giovanni Piredda]

I would like to try the graphing command with the SVN version of TeXmacs 
(revision 12509). I have a question on installation.


As far as I understand, I have to compile it from source; for this I 
need Guile 1.8.

How do I install Guile 1.8 without affecting the rest of my system 
(Xubuntu 18.04) where I have a more recent version of Guile which I want 
to keep as "default"? I have tried to do it with the package manager (I 
must have downloaded the package some time ago, as I found it on 
Synaptic!) and I get the following error message:

E: 
/var/cache/apt/archives/guile-1.8-dev_1.8.8+1-8ubuntu3-bionic_amd64.deb: 
trying to overwrite '/usr/bin/guile-config', which is also in package 
guile-2.0-dev 2.0.13+1-5ubuntu0.1

which seems sensible. A brief search on the Internet did not help. 
Thanks in advance for your suggestions.
